350 roller block bored .030" over
stock bottom end, rebuilt with hyperutectic pistions. 9.35:1 /w 64cc heads
Aluminum Vortec Heads, 62cc combustion chamber, 210cc intake, 78 cc exhaust. 2.00int 1.55 exh valves
Edelbrock Performer RPM intake (Vortec)
havn't got a carb yet, leaning towards the Holley Street Avenger 770CFM

it's the second vehical, to be driven to and from the track and on sundays.. (sometimes on saturday nights)
it's going to be mated to a 700r4 transmission and the torque converter is as of yet, undetermined..

what cam would be good with this? i've been playing on DD2000 and the ZZ3 cam seems nice... but..
zz3 cam
roller
cam specs@: seat to seat
int 0.474"
exh 0.510"
lobe center 113.8
valve overlap 50.0
int. dur 275.0
exh. dur 280.0

the duration for the intake and exhaust seem a bit odd to me. I'm just wondering if it's the Advance Duration or something.. any other suitable cams out there that might be friendlier (if that isn't the advance duration)..
opinions greatly apreciated.

Make sure the valve guides have been cut down to accept that much lift. Stock Vortec heads will only tolerate about .460" - .480" before the retainers smash into the top of the guides. But since there are no stock aluminum Vortec heads as such, who knows what you'll get inthat dept. If those are the Edlebrock heads then I would assume that they don't suffer from the same non-performance issues as stock Vortecs.

I don't see anything the least bit odd about the duration numbers. That cam is something like 216°/226° @ .050" IIRC, real mild like most all stock cams. If you're wanting to go fast I think you can do alot better with an aftermarket cam.

 

The cam will be directly tied to the torque converter stall speed.

I would go with a solid roller cam for a street strip car like yours.
Check out Comp cams extreme energy solid street roller series of cams. decide what stall converter you're willing to live with and select a cam that is just comming on its power band at the stall speed rpm.
I would go with a 3500 stall converter and one of these mechanical street rollers.

These are tight lash, low noise, low fuss, but powerfull street roller grinds. The will cost less than a hyd roller and perform better.

Since it is a second vehicle and you are interested in going to the track with it, I'd strongly consider useing a TH350 trans over the 700r4 (much cheaper to build, faster down the track,
much more choice in converters, more reliable too.)
